struct
(struct package-output (name steps make-subprogram))
name : string? steps : list? make-subprogram : (-> subprogram?)
A package output is an instance of package-output.
Each instance represents a named subprogram that claims to follow the
instructions shown in steps.
Specifically, steps is a list of syntax objects or data that are suitable for use in mdo.
make-subprogram returns a subprogram that creates files. The subprogram does not need to be atomic, but it should mirror the content of steps.
procedure
(find-package-output name steps) → (or/c #f package-output?)
name : string? steps : (listof package-output?)
Like findf, except the input list must consist of
package outputs, and the search will only compare names.
procedure
(encode-package-output to-encode) → list?
to-encode : package-output?
Any output created using output in the denxi or denxi/pkgdef languages are suitable for use with encode-package-output.
Returns a quoted output term suitable for use in a
package definition. The term will use the elements of
(package-output-steps to-encode), which means the correctness
of the returned list depends on if (package-output-steps to-encode) and (package-output-make-subprogram to-encode) are
equivalent.
syntax
(transparent-package-output name step ...)
name : non-empty-string?
Expands to a new package-output where the
package-output-steps and
package-output-make-subprogram fields both use the provided
sequence of steps.
Specifically, package-output-steps is '(mdo step ...) and package-output-make-subprogram is (lambda () (mdo step ...)).
